coding agent leaderboards can no longer rank their top entries. a september 15 audit of 254 swe-bench submissions found the leading two agents each resolve 396 of 500 instances, solving the same 285 and failing the same 51, with scaffold differences moving scores by 30 points. the spread you see is mostly the harness, not the model.

The air is now being asked to keep its own ledger
the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.
